This invention relates to brackets, commonly called Window-jacks,forsupporting scalfoldin g against the side of a dwelling; and the objectof the same is'to provide a bracket of this character which may be runout from any Window and which will support the scaffolding around thecorner of a dwelling.

To this end theinvention consists of the details of constructionhereinafter more fully described and claimed, and as illustrated in theaccompanying drawings, in which- Figure 1 is a perspective view showingmy device as used to support a staging along one side and beyond thecorner of a house. Fig. 2 is a similar View showing two of my bracketsas arranged to support a short staging near the top of a Window or anyplace on the casing you wish to use it. Fig. 3 is aside elevation of onebracket. Fig. Llis a similarview showing the preferred form of bracetherefor. Fig. 5 is a perspective view showing the manner in whichtheinner ends of thebrackets are locked in the window. Fig. 6 is aperspective det-ail of the locking-bar with one of its cushions removed.Fig. 6X is asimilar view of an extension locking-bar. Fig. 7 is anenlarged perspective view of another form of loop for holding thelocking-bar. Fig. 8 is a perspective detail of the several parts of thecorner attachment of my improved device. Fig. 9 is a perspective View ofa window, showing my device as used as a window-cleaning staging.

Referring to the said drawings, the letter A designates the bracketproper, comprising an upright and ahorizontal member connected by aninclined brace B. This brace is preferably composed of gas-pipe, asshown in Fig. 4, and C C are brackets secured to the lower end of theupright member and the outer end of the horizontal. When the gas-pipe Bis used, these brackets have reduced inner ends c, which t into the endsof the pipe; but at other times the brace B is continued into thebrackets C C, and is also preferably continued completely around theends of the upright and horizontal members. At the end of the latter theiron is turned up to form a hook D, for a purpose to appear hereinafter;and at the lower end of the upright member, the iron is turned alsoupwardly into a hook E, adapted to receive a cross-bar F, also forapurpose to be described below. Near the rear end of the horizon talmember of the bracket and on ,its under side is a loop G, into the rearend of which passes a long screw H, and I is across-bar of asize to passthrough the loop G. At each end of this cross-bar is a plate J, having aslot K in its body provided with an enlarged end L, and M is a cushionhaving a headed stud N, provided with an angular body of a size to turnwithin the enlarged end L, but to slide within the slot K withoutturning. At the rear side of the angle between the horizontal andupright members is a hook O. (Best seen in Fig. Vhen the abovedescribedbracket is to be fastened outside of a window, the inner end of thehorizontal member is passed through the window, as seen in Figs. 2 and5. The

cross-bar I is passed through the loops IG and v its cushions M adjustedso as to'bear against the inner faces of the sides of the windowframe.An outer cross-bar P is placed in the hooks O, with its ends resting onthe outer faces of the window-frame, and the screws H are tightened toclamp the bars I andP upon the frame. If the brackets are to be adjusted near the top of the window, the cross-bar F is inserted inthehooks E,with its ends bearing against the window-frame below the barP, Fig. 2 5 but if the brackets are to be adjusted at the bottom of thewindow the hooks E will be allowed to bear against the outer side of thewall, as shown in Fig. 9, in which case the hooks O will stand justunderneath the window-sill and the cross-bar P may be then omitted. Whentwo brackets are fastened in one window, the brace-rods q and r aresecured in the brackets C C by set-screws t, as seen in Figs. 2 and 9.'When it is desired to support a staging alongside a building, onebracket may be connected to each of two windows. In this case the samecross-bars are used, but the bracket is located close to the side of thewindow, thereby doing away with bar r to connect them, as in Fig. 2.Boards Q are laid upon the outer end of the horizon- IDO tal member ineithercase; but the boards of the staging are of course longer, andthehooks D at the outer ends of the horizontal members prevent theboards from slipping olf, which would precipitate to the ground anyperson or persons who were standing thereon.

Where the window is provided with inside blinds, it will be obvious thatthe cross-bar I, with the cushions V, cannot be employed. In this case Iprovide a cross-bar I', which is plain, and instead ofthe loops G, I useloops G'. (Best seen in Fig. 7.) Each of such loops has a hook 1Wadapted to pass under the inner edge of the window-sill and providedwith a square body and a reduced and threaded upper end N', upon whichis a thumb-nut O. The square body of this hook passes through asimilarly-shaped opening K' in the loop, which prevents its turning, soas to slip lfrom beneath the sill. In this case the loop G' comprisesupper and lower members, and to the lower member, at J', is hinged ablock L', whose upper end is notched, as at Z', so as to straddle theupper membenof the loop. The inner end of this member is threaded, asshown, and athumb-nutj' engages it. In operation the plain cross-bar I'is passed through the two loops G', the hooks M' engage beneath thesill, the blocks L' turned up so as to cause their notches l' to engagethe upper members of the loops, and the thumb nutsj' turned home topress the bar I' toward the sill.

At the junction between the horizontal and vertical members of one or ofboth brackets, preferably upon its inner face, is a cleat R, and uponthe vertical member near its lower end on its outer face is anothercleat S, and

into these cleats is adapted to be locked an extension-bracket T,comprising two members, secured at right angles to each other andconnected by a diagonal brace t'. The inner member has an L-shaped ironU secured to its upper face and adapted to pass over the bracket properA and [it within the cleat R, and this member has also an eye V on itsunder face near its outer end. The outer member has a cleat W near itsouter end. X X are braces, the former having a hook Y at its upper endadapted to engage the eye V and the latter having an iron Y at its upperend adapted to engage the cleat W, and both braces have irons Z attheirlower ends adapted to tit within the cleat S, of which they arenecessarily one half the width. When these braces are in position, theextension-bracket T is supported by the bracket A, with its outer memberparallel with the 4horizontal member ot the main bracket A, as best seenin Fig. l. This extension bracket is useful, as here shown, forsupporting the ends of long staging-boards, which project beyond themain bracket A and extend beyond the corner of the building, and whennot in use the extension-bracket and its braces can be removed andstored away.

v In Fig. 9 I have illustrated one use to which my improved bracket can`be put. In this case two of the brackets are supported upon and outsideof a window-sill, and on these brackets are supported shortflooring-boards Q. The horizontal members of the brackets outside thewindow carry staples or eyes a and b, the latter being somewhatthesmaller, and in these eyes are supported uprights d, whose bodies passthrough the upper eyes and whose reduced lower ends tit in the lowereyes, as will be understood. Through openings in the upper ends of theseuprights is passed a ropef. This device is used by domestics forcleaning windows, the .rope preventing their falling.

In Fig. 6X is shown across-barlof slightlyditterent construction fromthat shownin Fig. G-that is to say, the ends of the bar are constructedin the same manner and carry the cushions M in the same way; but the baris broken-at its center. An extension-piece 20 is here inserted, itsendlapping the inner ends of the members 2l ot' the broken bar. Strapsor clamps 22 are passed around the lapping ends, and set-screws 23 areinserted through these straps, as shown. lVith this improved bar, whenit is desired to adjust the same to windows of variable widths, theset-screws 23 are loosened, the members 2l are slipped through thestraps 22 to the proper points, and the set-screws 23 again tightened tohold the parts in adjusted position.

In Fig. 3 I have shown in dotted lines another long screw HX, 'whichpasses through the other end of the loop G, and this screw I sometimesuse in addition to thatlettered H, whereby it is possible to adjust thebar- I at different points within the loop G than against the inner endthereof, as would be possible it the screw H only were used.

By the use of my improved device windows may be cleaned or repaired andhouses may be painted from the ground to the eaves and around alldilicult corners, providing only thatl windows or doors occur in thatside of the house' and that the studding will permit the attachment ofthe brackets, and in this manner the use of the pendent staging so oftenemployed by painters and others `with disastrous and fatal results tothemselves and to passers-by is done away with.

The device is made of any suitable material, preferably wood, with metalcleats, sockets, and hooks, and is finished in any desired manner. andas it occupies but a small space can be stored away in a closetorcupboard when not in use.
